Pardon my stupidity, but how about using a linear solenoid attached to a 
spring? It would be easy enough to attach a strain gauge to the end of the 
actuator, or you could use a current-sensor to provide feedback. This will 
provide linear pulling force, stores elastic potential energy, sensing 
capability, and has zero mecha.... OOPS! never mind.
